RSS Versions

RSS has a sordid history. Different people and groups have largely unilaterally created specifications that they called RSS. Some RSS formats are XML-based formats. And some RSS formats are RDF-based formats.

The list below is of all known RSS versions. They are listed in chronological order of when they were released.

NOTE: In the list below, although RSS 1.0 seems to be out of place, it is actually in the correct place chronologically.
